Description
Technical field
The utility model relates to a kind of liquid subpackage device, particularly the liquid subpackage measuring fixed amount device of a kind of applicable hospital packing liquid drug.
Background technology
In hospital, usually need the liquid drug in large-rolume container to divide in the container that installs to low capacity, then divide and install to each ward use.For packing dosage is accurate, when packing, need to measure out quantitative liquid with graduated cylinder, and then pour in small container.Divide process of assembling comparatively loaded down with trivial details, inefficiency.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of easy to operate, the liquid subpackage measuring fixed amount device of accurate measurement.
The technical scheme in the invention for solving the technical problem is: a kind of liquid subpackage measuring fixed amount device, is characterized in that: comprise drug taking tube and quantitative separating device, drug taking tube head end connects the feeding opening of quantitative separating device; Described quantitative separating apparatus body is partly a tubbiness housing, has a piston in housing, and piston top connects a push rod, and push rod is through case top lid interstitial hole, and push rod is topmost one discoid by hand; By there being a spring being nested in outside push rod between hand and case top lid; One feeding opening is arranged at housing wall top, and a medicine outlet is arranged at bottom, has a hole on piston, and feeding opening connects drug taking tube, and medicine outlet is respectively connected a check valve with the hole on piston; There is interior convex edge housing inside upper part feeding opening below; On housing outer wall, have a supporting seat, there is vertical tapped bore supporting seat inside, passes the leading screw adapting with tapped bore screw thread in tapped bore, is the described hand of pressing directly over leading screw.
Above-mentioned drug taking tube end has a filter screen.
On above-mentioned housing outer wall, the position corresponding with leading screw indicates scale.
Compared with prior art, the utlity model has beneficial effect easy to operate, accurate measurement.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model.
Fig. 2 is that quantitative separating device of the present utility model is faced structural representation.
Fig. 3 is the left TV structure schematic diagram of quantitative separating device of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises quantitative separating device 4 and drug taking tube 3, and drug taking tube 3 head ends connect the feeding opening of quantitative separating device 4, and drug taking tube 3 ends are placed in the liquid of large capacity drug reservoir 1.At drug taking tube 3 ends, there is a filter screen 2, can prevent that foreign matter from flowing into quantitative separating device 4 with liquid.
As shown in Figure 2, its base portion is a tubbiness housing 9 to the structure of described quantitative separating device 4, has a piston 10 in housing 9, and piston 10 tops connect a push rod 8, and push rod 8 is through housing 9 upper cover interstitial holes, and push rod 8 is topmost one discoid by hand 5.By there being a spring 6 being nested in outside push rod 8 between hand 5 and housing 9 upper covers, spring 6 is in compressive state.
One medicine outlet is arranged at housing 9 wall bottoms, has a hole on piston 10, and medicine outlet is respectively connected a check valve with piston hole.The effect of check valve is that liquid can only be flowed towards a direction, can not reverse flow.As shown by arrows in FIG., piston 10 place's check valves 11 flow downward liquid to the flow direction of two check valves, and medicine outlet place check valve 12 makes liquid flow out quantitative separating device 4.
There is interior convex edge 7 housing 9 inside upper part feeding opening 12 belows, and its effect is when piston 10 rises to herein, block piston 10 and make it no longer continue to rise.
As shown in Figure 4, on described housing 9 outer walls, there is a supporting seat 14.There is vertical tapped bore supporting seat 14 inside, separately have a leading screw 13 that passes tapped bore and adapt with tapped bore screw thread.When rotational lead screw 13, leading screw 13 can up-and-down movement.Directly over described leading screw 13, for pressing hand 5, leading screw 13 has played space to be stopped by the effect of hand 5 displacements, while pressing by hand 5, can be blocked by leading screw 13 upper ends, make its can not continue under by.
Under state of nature, because the elastic force piston 10 of spring 6 is stuck in 7 places, interior convex edge, when pressing by hand 5 primary pistons 10, move downward, after being blocked by leading screw 13 by hand 5, motion stops, liquid in this process in quantitative separating device 4 is extruded and discharges from medicine outlet, and the amount of discharge depends on the stroke of piston 10.Meanwhile, because quantitative separating device upper space increases, liquid is sucked into quantitative separating device by drug taking tube 3 from large capacity drug reservoir 1.After unclamping, due to the elastomeric effect of spring 6, by hand 5, upspring, piston 10 returns to 7 places, interior convex edge.It is large that the volume of quantitative separating device 4 inner carrier 10 bottoms becomes, and liquid flows to the bottom of quantitative separating device 4 from piston 10 check valves 11.
By the position of rotating threaded shaft 13 adjusting screws 13, can change the stroke of piston 10, thereby change the dose of discharging.
Position corresponding with leading screw 13 on housing 9 outer walls indicates scale 15, shows the drug row amount of quantitative separating device 4.
Operating process is as follows: the position of first adjusting screw 13 while using first, by scale 15, adjust the drug row amount of quantitative separating device 4, and while getting it filled, only need press by hand 5 until blocked and can take out quantitative liquid by leading screw 13 by hand 5 later at every turn.
It should be noted that; particular of the present utility model have been described in detail the utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
